A Philadelphia retail complex has hired the help of a South Jersey entertainment company to help drown out a loud — offensive to many — protest group, according to a report from Philly.com.

Joe Moser, 32, and Eric Pawlicki, 23, of Moorestown-based DJ's Available, are used to battling loud conversation at bars, clubs and private parties.

But just about every Friday they battle a different group of revelers — The Israelite School of Universal and Practical Knowledge, also known as the "Black Israelites."

The group moved its demonstrations to the Shops at Liberty Place after spending 20 years at the Gallery at Market East.

"My family and I will never be shopping at Liberty Place again due to this outrageous, and frankly quite frightening display of ethnic intimidation and flat out scary demonstration by a group that was at your mall yesterday around 4 p.m.," one patron wrote to Liberty Place last May.

"When my children feel the need to grip on to me due to sheer terror at people protesting with very graphic signs and photos, that's where I draw the line," the patron added.

The group selected the location because of a massive violent fight involving 200 schoolchildren at 16th and Chestnut streets in April 2013, according to the report.

Liberty Place filed a lawsuit against the Black Israelites last May, the report said, but a judge ruled in favor of the group, citing its First Amendment rights.

"I believe in freedom of speech, they have the right to say how they feel," Moser told Philly.com. "I just wish the things that they said were more positive."

The group believes in a radical black-separatist ideology, and ridicules white people, women, homosexuals and anyone who does not support its beliefs, the report said. A member of the Black Israelites told Philly.com he believes Rev. Dr. Martin Luther King Jr. was the biggest terrorist to black people because he sold them out.

"They wish death on people, they say they hope everyone dies on their way home and gets cancer," Pawlicki told the news site. "I'm there to drown them out, and turn a negative into a positive."
